Bram Moolenaar | a9aafe5 | 2008-05-07 11:10:28 +0000 | [diff] [blame] | 4508 | * sub_firstline The old text, unmodified. |
Bram Moolenaar | 071d427 | 2004-06-13 20:20:40 +0000 | [diff] [blame] | 4509 | * copycol Column in the old text where we started |
| 4510 | * looking for a match; from here old text still |
| 4511 | * needs to be copied to the new text. |
| 4512 | * matchcol Column number of the old text where to look |
| 4513 | * for the next match. It's just after the |
| 4514 | * previous match or one further. |
| 4515 | * prev_matchcol Column just after the previous match (if any). |
| 4516 | * Mostly equal to matchcol, except for the first |
| 4517 | * match and after skipping an empty match. |
| 4518 | * regmatch.*pos Where the pattern matched in the old text. |
| 4519 | * new_start The new text, all that has been produced so |
| 4520 | * far. |
| 4521 | * new_end The new text, where to append new text. |
| 4522 | * |
Bram Moolenaar | bd7cc03 | 2008-01-09 21:40:50 +0000 | [diff] [blame] | 4523 | * lnum The line number where we found the start of |
| 4524 | * the match. Can be below the line we searched |
| 4525 | * when there is a \n before a \zs in the |
| 4526 | * pattern. |
Bram Moolenaar | 071d427 | 2004-06-13 20:20:40 +0000 | [diff] [blame] | 4527 | * sub_firstlnum The line number in the buffer where to look |
| 4528 | * for a match. Can be different from "lnum" |
| 4529 | * when the pattern or substitute string contains |
| 4530 | * line breaks. |
| 4531 | * |
| 4532 | * Special situations: |
| 4533 | * - When the substitute string contains a line break, the part up |
| 4534 | * to the line break is inserted in the text, but the copy of |
| 4535 | * the original line is kept. "sub_firstlnum" is adjusted for |
| 4536 | * the inserted lines. |
| 4537 | * - When the matched pattern contains a line break, the old line |
| 4538 | * is taken from the line at the end of the pattern. The lines |
| 4539 | * in the match are deleted later, "sub_firstlnum" is adjusted |
| 4540 | * accordingly. |
| 4541 | * |
| 4542 | * The new text is built up in new_start[]. It has some extra |
| 4543 | * room to avoid using alloc()/free() too often. new_start_len is |
Bram Moolenaar | 61abfd1 | 2007-09-13 16:26:47 +0000 | [diff] [blame] | 4544 | * the length of the allocated memory at new_start. |
